Ubuntu 16.04 LTS NVIDIA Setup Guide

[jimbas]

Hi,

just added a new GTX 1080 to my current rig.
I'm running Ubuntu 16.04 Server and I was able to control my 2 GPUs with this guide and nvidia-settings commands.

Here's my nvidia-smi:

Code:

It looks like my GPU 1 (new one) is not fully "working".
Hashcat can control its fan, but when I do:

Code:

nvidia-settings -a [gpu:1]/GPUFanControlState=1 -a [fan-1]/GPUTargetFanSpeed=100

my nvidia-smi:

Code:

+-----------------------------------------------------------------------------+

and when I do:

Code:

nvidia-settings -a [gpu:2]/GPUFanControlState=1 -a [fan-2]/GPUTargetFanSpeed=100

I recive this message:

Code:

ERROR: Error assigning value 100 to attribute 'GPUTargetFanSpeed' (horse-power:0[fan:2]) as

      specified in assignment '[fan-2]/GPUTargetFanSpeed=100' (Unknown Error).

It looks like GPU number it's not assigned correctly.. any ideas ?

Thanks in advance
